NCT01625143

Brief Summary

This laboratory study is looking into genes in samples from younger patients with relapsed acute lymphoblastic leukemia. Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors find better ways to treat cancer.

Outcome Measures

Primary Outcomes (3)

  • Cellular origins of relapse and the underlying epigenetic mechanisms associated with drug resistance

    1 month

  • Genes associated with histone modification

    1 month

  • Biological pathways involved in relapse

    1 month

Study Arms (1)

Observational

Archived bone marrow samples, collected at the time of diagnosis and relapse, are analyzed for gene expression and histone modifications by microarray, chromatin immunoprecipitation (ChIP) sequencing, and quantitative real-time polymerase chain reaction (qRT-PCR).

Other: laboratory biomarker analysis
